This is more of a rant than request for assistance with troubleshooting.
Due to family health reasons, my wife and I are planning to relocate sometime in April/May. So after we've decided to try to sell my 2003 Elantra rather than replace the rear right brake caliper and patch the exhaust, my wife's 2010 Accent hatchback (automatic) threw a CEL yesterday after work. What was really fun is the O/D light was flashing...all strobe lights strive to flash so quickly. The car seems like it's stuck in 3rd gear and won't display the state of the transmission on the HUD. (No P, R, N, D, 2, or 1 is displayed.) When putting it into drive it lurched forward. I drove the vehicle home as gently as possible after verifying that the transmission fluid levels were okay and didn't smell burned. (Note that the CEL was solid and not flashing.)
My OBD scanner is showing the error U0101 "generic." (Lost Communication With Transmission Control Module) After looking it up, from what I can tell, it's an error that could be related to a number of things but may require a replacment TCM. I have an appointment with the dealership as I'd rather them diagnose a possible electric/computer problem than my regularly trusted mechanic. These past few months have been expensive and this is not something that was expected. Why when it rains must it pour.
